Question

A car moves a distance of 100m with a constant speed of 50m/s and move the next 100m with 100m/s then find average speed.​

Answer 1

Answer:

Average speed is $\frac{200}{3}$m/s

Explanation:

We know speed = $\frac{Distance}{Time}$

For the first 100m,

Speed = 50m/s

Distance = 100m

Therefore time = 100/50 = 2s

For the next 100m,

Speed = 100m/s

Distance = 100m

Therefore time = 100/100 = 1s

Therefore average speed = $\frac{Total distance}{Total time}$

                                           = $\frac{100+100}{2+1}$

                                           = $\frac{200}{3}$m/s
